[0079] In the embodiments of the present disclosure, a method for energy management of an electric vehicle is provided, and a corresponding processing flow can be as shown in Figure 4 The method comprises the following steps:

[0080] 401. The solar controller 3 acquires the first state of charge of the power battery 4 and the second state of charge of the weak-current battery 5.

[0081] The battery management system of the power battery 4 can determine the first state of charge of the power battery 4 according to the voltage of the power battery 4. The solar controller 3 can acquire the first state of charge of the power battery 4 from the battery management system of the power battery 4.

[0082] The solar controller 3 can acquire the voltage of the weak-current battery 5, and determine the second state of charge of the weak-current battery 5 based on the voltage of the weak-current battery 5.

[0083] 402. The solar controller 3 charges the power battery 4 or the weak-current battery 5 based on the first state of charge and the second state of charge.

[0084] The solar controller 3 determines whether to charge the power battery 4 or the weak-current battery 5 according to the first state of charge and the second state of charge.

[0085] In a possible implementation, the process in which the solar controller 3 charges the weak-current battery 5 can comprise the following steps as shown in Figure 5

[0086] 501. When the second state of charge is less than a first threshold, the solar controller 3 starts to charge the weak-current battery 5.

[0087] The solar controller 3 calculates the second state of charge of the weak-current battery 5 in real time. If the solar controller 3 determines that the second state of charge is less than the first threshold at a certain moment, the solar controller 3 starts to charge the weak-current battery 5 when the solar controller 3 is not charging the weak-current battery 5. When the solar controller 3 is charging the weak-current battery 5, the solar controller 3 continues to charge the weak-current battery 5.

[0088] ​If the solar controller 3 determines that the second state of charge is greater than the first threshold value at a certain moment, when the solar controller 3 is not charging the weak current battery 5, the solar controller 3 does not charge the weak current battery 5, and when the solar controller 3 is charging the weak current battery 5, the solar controller 3 continues to charge the weak current battery 5.

[0089] The first threshold value can be pre-set by a technician, for example, it can be 95%, that is, when the second state of charge is less than 95%, the solar controller 3 starts to charge the weak current battery 5.

[0090] 502, when the second state of charge is greater than the second threshold value, the solar controller 3 ends charging the weak current battery 5.

[0091] The second threshold value is greater than the first threshold value.

[0092] The solar controller 3 calculates the second state of charge of the weak current battery 5 in real time, and if the solar controller 3 determines that the second state of charge is less than the second threshold value at a certain moment, when the solar controller 3 is charging the weak current battery 5, the solar controller 3 continues to charge the weak current battery 5.

[0093] If the solar controller 3 determines that the second state of charge is greater than the second threshold value at a certain moment, when the solar controller 3 is charging the weak current battery 5, the solar controller 3 ends charging the weak current battery 5. When the solar controller 3 is not charging the weak current battery 5, the solar controller 3 does not start charging the weak current battery 5.

[0094] The second threshold value can be pre-set by a technician, for example, it can be 98%, that is, when the second state of charge is greater than 98%, the solar controller 3 ends charging the weak current battery 5.

[0095] When the second state of charge is less than the sixth threshold value, the solar controller 3 sends an alarm signal. The sixth threshold value can be 30%, at which time the weak current battery 5 may be malfunctioning, and the solar controller 3 sends an alarm signal to timely remind the user to check the possible malfunction. When the second state of charge is less than the seventh threshold value, the power battery 4 charges the weak current battery 5. For example, the seventh threshold value can be 60%, when the second state of charge is less than 60%, only the solar controller charging the weak current battery 5 is not enough for the weak current battery 5 to supply power to the weak current electrical appliances, at which time, the power battery 4 needs to charge the weak current battery 5, so that the weak current battery 5 normally supplies power to the weak current electrical appliances in the vehicle.

[0096] In a possible implementation, the process in which the solar controller 3 charges the power battery 4 can be as shown in Figure 6 The process includes the following steps:

[0097] 601, when the solar controller 3 is not charging the weak current battery 5, and the first state of charge is less than the third threshold value, the solar controller 3 starts to charge the power battery 4.

[0098] The solar controller 3 obtains the first state of charge of the power battery 4 in real time. If the solar controller 3 determines that the first state of charge is less than the third threshold value at a certain moment, when the solar controller 3 is not charging the weak current battery 5, the solar controller 3 starts to charge the power battery 4, and when the solar controller 3 is charging the weak current battery 5, the solar controller 3 continues to charge the power battery 4.

[0099] If the solar controller 3 determines that the first state of charge is greater than the third threshold value at a certain moment, when the solar controller 3 is not charging the power battery 4, the solar controller 3 does not start to charge the power battery 4.

[0100] The third threshold value can be pre-set by the technician, for example, it can be 95%, that is, when the first state of charge is less than 95%, the solar controller 3 starts to charge the power battery 4.

[0101] When the solar controller 3 is charging the weak current battery 5, the power battery 4 is not charged.

[0102] 602, when the solar controller 3 is not charging the weak current battery 5, and the first state of charge is greater than the fourth threshold value, the solar controller 3 stops charging the power battery 4.

[0103] The fourth threshold value is greater than the third threshold value.

[0104] The solar controller 3 obtains the first state of charge of the power battery 4 in real time. If the solar controller 3 determines that the first state of charge is less than the fourth threshold value at a certain moment, when the solar controller 3 is not charging the weak current battery 5 and is charging the power battery 4, the solar controller 3 continues to charge the power battery 4, and when the solar controller 3 is charging the weak current battery 5, the solar controller 3 does not charge the power battery 4.

[0105] If the solar controller 3 determines that the first state of charge is greater than the fourth threshold value at a certain moment, when the solar controller 3 is charging the power battery 4, the solar controller 3 stops charging the power battery 4, and when the solar controller 3 is not charging the power battery 4, the solar controller 3 does not start to charge the power battery 4.

[0106] The second threshold value can be pre-set by the technician, for example, it can be 98%, that is, when the first state of charge is greater than 98%, the solar controller 3 stops charging the power battery 4.

[0107] In a possible implementation, the electric vehicle can further include an air conditioner controller 6 and a blower 7. The air conditioner controller 6 is electrically connected with the blower 7, and the air conditioner controller 6 and the blower 7 are electrically connected with the solar controller 3. The process that the solar controller 3 supplies power to the blower 7 can be as shown in FIG. 8, including the following steps. Figure 7

[0108] 701. When the second state of charge is greater than the fifth threshold value, the solar controller 3 informs the air conditioner controller 6 to start the external circulation mode, and starts to supply power to the blower 7.

[0109] The fifth threshold value is less than the first threshold value.

[0110] The solar controller 3 calculates the second state of charge of the weak current battery 5 in real time. If the solar controller 3 determines that the second state of charge is greater than the fifth threshold value at a certain moment, whether the solar controller 3 is charging the weak current battery 5 or not, the solar controller 3 informs the air conditioner controller 6 to start the external circulation mode, and starts to supply power to the blower 7.

[0111] The fifth threshold value can be set by the technician in advance, for example, it can be 85%, that is, when the second state of charge is greater than 85%, the solar controller 3 informs the air conditioner controller 6 to start the external circulation mode, and starts to supply power to the blower 7.

[0112] 702. When the second state of charge is less than the fifth threshold value, the solar controller 3 informs the air conditioner controller 6 to close the external circulation mode, and stops to supply power to the blower 7.

[0113] The solar controller 3 calculates the second state of charge of the weak current battery 5 in real time. If the solar controller 3 determines that the second state of charge is less than the fifth threshold value at a certain moment, when the air conditioner controller 6 is starting the external circulation mode, and the solar controller 3 is supplying power to the blower 7, the solar controller 3 informs the air conditioner controller 6 to close the external circulation mode, and stops to supply power to the blower 7.

[0114] The fifth threshold value can be set by the technician in advance, for example, it can be 85%, that is, when the second state of charge is greater than 85%, the solar controller 3 informs the air conditioner controller 6 to start the external circulation mode, and starts to supply power to the blower 7.

[0115] In a possible implementation, the process that the air conditioner controller 6 controls the blower 7 can be as shown in FIG. 8, including the following steps.

[0116] 801. Obtain the current temperature in the electric vehicle, and obtain the electric power currently received by the solar controller 3 from the solar panel 2.

[0117] ​The temperature sensor can be installed in the vehicle to detect the temperature in the vehicle in real time, and the air conditioner controller 6 can obtain the current temperature in the vehicle from the temperature sensor.

[0118] The solar controller 3 can currently receive the electric power of the solar panel 2, and the air conditioner controller 6 can obtain the electric power currently received by the solar controller 3 from the solar panel 2.

[0119] 802, in the case that the current temperature in the vehicle is greater than the first reference temperature and the electric power is less than the first reference electric power, determining a first difference between the current temperature in the vehicle and the first reference temperature, and determining a second difference between the first reference electric power and the electric power, determining a first ratio of the first difference to a third difference, the third difference being a difference between the second reference temperature and the first reference temperature, determining a second ratio of the second difference to a fourth difference, the fourth difference being a difference between the first reference electric power and the second reference electric power, and determining the target output power of the blower 7 based on the first ratio and the second ratio.

[0120] The first reference temperature, the first reference electric power, the second reference temperature, and the second reference electric power can be pre-set by the technician based on experience, and the air conditioner controller 6 can pre-store the first reference temperature, the first reference electric power, the second reference temperature, and the second reference electric power. For example, the first reference temperature is 24 degrees Celsius, the first reference electric power is 40 watts, the second reference temperature is 50 degrees Celsius, the second reference electric power is 100 watts, the third difference is 26 degrees Celsius, and the fourth difference is 60 watts.

[0121] For example, the current temperature in the vehicle is 30 degrees Celsius, the first difference is 6 degrees Celsius, the current electric power is 30 watts, the second difference is 10 watts, the first ratio is 3 / 13, and the second ratio is 1 / 6.

[0122] Based on the first ratio and the second ratio, the target output power of the blower 7 is determined. The ratio of the first ratio and the second ratio is calculated as a third ratio, and the air conditioner controller 6 can pre-store a corresponding relationship between the ratio and the output power of the blower 7. The output power corresponding to the third ratio is found in the corresponding relationship as the target output power of the blower 7.

In the case that the current temperature in the vehicle is greater than the first reference temperature and the electric power is greater than the first reference electric power, the air conditioner controller 6 determines the target output power based on the current temperature in the vehicle in the corresponding relationship.
